Norgren RM/960/125 Pneumatic Cylinder - 6-inch Bore, 125 mm Stroke
Part Number: RM/960/125
Quick Summary
Norgren RM/960/125 pneumatic cylinder provides dependable linear actuation for automation lines and material handling. Engineers frequently face cushioning wear, misalignment, and downtime on high-cycle cylinders; this model mitigates those issues with adjustable cushioning and a rugged tie-rod design. CE-compliant safety expectations, IP-rated enclosures, and SIL-ready options are standard considerations in modern factories for this class of actuator. With a 6-inch bore and 125 mm stroke, it delivers substantial force while staying compact, enabling higher throughput and lower total cost of ownership in industrial automation. Its compatibility with the RM/900 range simplifies spares and maintenance, while the non-magnetic piston rod supports sensor-based automation in mixed-material environments.

The tie-rod, double-acting design delivers balanced thrust in extend and retract strokes, reducing setup time and improving repeatability in demanding automation tasks. This translates to faster cycle times and fewer positional errors on pick-and-place and clamping stations, especially when handling heavier parts. The cylinder’s 6-inch bore enables a theoretical force of 10887 N, allowing reliable actuation of larger workpieces and higher-speed indexing in packaging lines and material handling. Adjustable cushioning minimizes impact and wear, protecting tooling and workpieces while reducing vibration-induced downtime on high-speed conveyors. The non-magnetic construction together with a stainless steel piston rod ensures sensor compatibility in automated systems that rely on magnetic sensing, enhancing reliability in steel and automated assembly environments. Compatibility with the RM/900 range and standard G1/2 fittings simplifies installation and spare-parts planning, reducing total cost of ownership. Operating between 2 and 10 bar and a wide temperature range of -20 to 80 C makes this cylinder suitable for diverse factory conditions, improving uptime and process stability in automated production lines.

FAQs
Mounting this model follows standard Martonair practices for tie-rod cylinders. Use compatible end-mittings and mounting feet designed for a 6-inch bore, ensure G1/2 port connections are sealed, and align the actuator to minimize side load. The RM/960/125 is designed for seamless integration with RM/900 components, and service kits QM/960/00 are available to support scheduled maintenance.
Operating pressure ranges from 2 to 10 bar (29 to 145 psi). The cylinder provides a theoretical force of 10887 N, enabling strong actuation for heavier loads and faster cycle times on demanding lines such as automated pick-and-place and clamp operations.
Yes. The double-acting design delivers reliable bidirectional thrust, and adjustable cushioning helps control impact, reducing wear on both the cylinder and tooling. Combined with stainless steel piston rod and anodised aluminium barrel, this model supports high-cycle performance in packaging, assembly, and material-handling lines while maintaining precision and repeatability.
The RM/960/125 is designed to meet common industry expectations for pneumatic actuators, including CE safety considerations and robust enclosure standards, with SIL-ready options where applicable. For precise certification and compliance details, consult the datasheet or contact Norgren to confirm current certifications for your region and application.
Service is supported by the QM/960/00 service kits, designed for RM/900-series cylinders. Regular maintenance includes inspecting cushioning, seals, and mounting hardware, and applying recommended lubricants. The robust build and available service kits help minimize downtime while extending the actuator’s service life in continuous-production environments.
